The most annoying thing for me currently is that when connecting to local smb shares with Finder and adding favorites (directories on shares), after a reboot they are still there under favorites, but it won't connect to them when clicking on them. So I have to manually reconnect to the server every time. This wasn't happening before.

Other than that, of course some things got slower, but overall it's an OK release. For example he new system settings were bad before, now they got a bit worse, but macOS 26 didn't introduce those changes.
